A system interface having a plurality of directors, one portion of such directors being adapted for coupling to a host computer/server and another portion of the directors being adapted for coupling to a bank of disk drives. The plurality of directors are interconnected through a network. A common resource section is provided having a resource shared among the plurality of directors. The common shared resource section includes a shared computer code used by the plurality of directors. The code includes computer code for booting up each one of the plurality directors. The common shared code storage section is interconnected to the directors through the network. A second, redundant common shared resource section is provided. The network is a packet switching network.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system interface comprising: plurality of directors, one portion of such directors being adapted for coupling to a host computer/server and another portion of the directors being adapted for coupling to a bank of disk drives, the plurality of directors being interconnected through a network; a common resource section for providing a resource shared among the plurality of directors; and wherein the common shared resource section includes a shared computer code used by the plurality of directors; and wherein each one of the directors accesses the shared code stored in the common shared resource in the shared resource section.
2. The system interface recited in claim 1 wherein the code includes computer code for booting up each one of the plurality directors.
3. The system interface recited in claim 2 wherein the common shared code storage section is interconnected to the directors through the network.
4. A system interface comprising: plurality of directors, one portion of such directors being adapted for coupling to a host computer/server and another portion of the directors being adapted for coupling to a bank of disk drives, the plurality of directors being interconnected through a network; a common resource section for providing a resource shared among the plurality of directors wherein the common shared resource section includes a shared computer code used by the plurality of directors; wherein each one of the directors accesses the shared code stored in the common shared resource in the shared resource section; and including second, redundant common shared resource section.
5. The system interface recited in claim 4 wherein second, redundant common shared resource section stores computer code used by the plurality of directors in the event the first mentioned one of the common shared code storage section fails.
6. The system interface recited in claim 4 wherein such system interface includes a second, redundant network coupled to the second shared resource section for use in interconnecting the directors in the event the first mentioned one of the shared resource sections fails.
7. A system interface comprising: plurality of directors, one portion of such directors being adapted for coupling to a host computer/server and another portion of the directors being adapted for coupling to a bank of disk drives, the plurality of directors being interconnected through a network; a common resource section for providing a resource shared among the plurality of directors wherein the common shared resource section includes a shared computer code used by the plurality of directors; wherein each one of the directors accesses the shared code stored in the common shared resource in the shared resource section; and wherein the network is a packet switching network.
8. The system recited in claim 7 wherein the redundant network is a packet switching network.
9. A system interface comprising: plurality of directors, one portion of such directors being adapted for coupling to a host computer/server and another portion of the directors being adapted for coupling to a bank of disk drives, the plurality of directors being interconnected through a network; a common resource section for providing a resource shared among the plurality of directors wherein the common shared resource section includes a shared computer code used by the plurality of directors; wherein each one of the directors accesses the shared code stored in the common shared resource in the shared resource section; and including a cache memory coupled to the directors and the shared resource though the network.
